Package
AC23C16200BFW : 44pin Plastic SOP(500mil)
AC23C16200BTR : 48pin Plastic TSOP-1(12x20mm)
AC23C16200BTF : 48pin Plastic TSOP-1(12x20mm)
AC23C16200BTT : 44pin Plastic TSOP-II(400mil)
The AC23C16200B high performance read only memory is organized either as 2,097,152 x 8 bit (byte mode)
or as 1,048,576 x 16 bit(word mode) followed by BHE mode select. The low power feature allows the battery
operation. The large size of 16M bit memory density is ideal for character generator, data or program
memory in micro-processor application. The AC23C16200B is packaged 44 SOP, 48TSOP-I and 44TSOP-II.

Stress above those listed under "absolute maximum ratings" may cause permanent damage to the
device. These are stress ratings only. Functional operation of this device at these or any other
conditions above those indicated in the operational sections of this specification is not implied and
exposure to absolute maximum rating conditions for extended periods may affect device reliability.
